1. What should be the L/D ratio assumption in Heat Exchanger Design/Rating in HTRI for below systems ?

     a. Liquid-Liquid

     b. Gas-Liquid

     c. Gas-Gas

 

2. How to reduce the overdesign in HTRI?

[Pilesar]

There is no standard L/D ratio assumption in Heat Exchanger Design/Rating in HTRI. Tubes come in standard sizes, so choose one that seems reasonable and then optimize the design. Reducing surface area is one way to reduce heat exchanger overdesign.

Hi,

Consider these documents support your work .

To me nothing is related to software , only good engineering practices .

Good luck

I you have access to Aspen EDR. It can provide you an estimate of optimized STHE based on a few factors. But you can surly design based on Engineering judgment, vendor communications etc.
